Featuring overclocking of the stream processors and equipped with upgraded -1 memory modules, users can expect over 40% improvement in gaming experiences, according to the Taiwanese company.

With the unified architecture of the GeForce 8 Series, NVIDIA utilizes stream processors to dynamically allocate processing power depending on the workload of the application. Therefore, performance and efficiency upgrades can be achieved by overclocking these stream processors. With the EN8600GT TOP, gamers can expect stream processor clock performance boosts from 1188MHz up to an 1458MHz.

Secondly, the EN8600GT TOP is upgraded with 1ns memory modules. "Such performance upgrades help raise the EN8600 GT TOP?s 3DMark06 score from 4185 to 5889 ? an 40% improvement in speed to any other reference designed board," Asus said.

The card comes with SmartDoctor, an overclocking utility that is able to tweak the Shader Clock on GPUs. With this application, users will be able to overclock the Shader Clock and Engine Clock independently without the hassles of rebooting or re-flashing their BIOS.

The ASUS EN8600GT TOP also comes with the exclusive ASUS GamerOSD to deliver GPU overclocking from onscreen displays during games.
